= Tooll whom it may concern:

Be it known that I, VILLIAM G. CRAMER, a citlzenof the United States, residing at B ufialo, n the county of Erie and State of 5 New York, have invented a new and useful Improvement in Sewer and Gutter Pipe Connections, of which the following is a specification. 1

This invention relates to the pipes employe'd for connecting the conductor or gutter pipe of a building with the sewer.

The object of the invention is the provision of a connection of this character which permits the ready'separation of the gutter .pipe from the pipe leading to the sewer, so that any accumulations or obstructions can be conveniently removed from the pipes, and the sewer can be flushed by water introduced at that point, if desired.

In the accompanying drawings: Figure 1 is "a side elevation of the connection, partly in section, showing the-same in its normal position. Fig. 2. is a vertical section, showing the,c onnec tion lowered to afford access to the separated pipes. Fig. 3 is a top plan view of the 'lower pipe. Fig. 4 is a cross section in line 44l Flg. 2.

' Similar letters of reference indicate correspending parts throughout the several views. A indicates a'lower pipep artly embedded in the ground and connected with the sewer, not shown; B indicates the conductor or gutter "pipe extending down from the cave-trough of the building and C an intermediate connection'or pipe connecting the gutter pipe with the lower pipe'A. The intermediate pi e is provided at its upper end with a mout 1 or socket (z-which receives the lower end of the gutter pipe and which is preferabl pro-- upon which rests a removable perforated plate or screen E.v This plate I intercepts sticks,

leaves, etc.,. preventing the same from dropinto the sewer and clogging it. The

-46'1ntermediate pipe 0 telescopes into thelower pipe A and. is provided with a transverse pin f, the ends of which project beyond its sides and normally engage seats or notches i g in the upper edge ofsaid lower pipe, thereby Q0 supporting the intermediate pipe in its elevated position in which it connects the gutter pipe with the lower pipe, as shown in Fig. 1.

at of line with the notches g, the lower pipe i Ais' provided with diametrically opposite 5'6 longitudinal 'slots h extending downward from its upper edge and adapted to receive the ends of the pinf. By this construction,

upon raising the intermediate pipe C to disthe lower pipe A sufliciently to withdraw its mouth 0 from the lower end of the gutter pipe, as shown in Fig. 2. In this position, the screen E and any accumulations thereon can be removed from the intermediate pi e and a hose or hose nozzle inserted in tie latter for flushing the pipe A and the sewer to which it' leads. After flushing the sewer, the screen -E is replaced and the intermediate pipe section is raised to its normal position and turned to seat its pin in the notches g. in order to permit-the intermediate pipe section to be lowered as above described, the slots h are sufiiciently longer than the mouth or portion of the pipe C which receives the gutter pipe, as shown in the drawings.

The intermediate pipe may be of uniform diameter throughout its len th, but the portion thereof immediately be 0w the screen E is preferably enlarged, as shown at i, and this enlargement contains one or more ventilating openings 7' by which the interior of said pi e and the gutter pipe communicate with t e outer atmosphere. By this construction an ascending draft or air current is created through the gutter pipe which dries its interim and prevents it from rusting. As the ventilating openings are located in the enlargements i where they are outside of the bore of the gutter pipe, the descending water passes directly through the pipe into the sewer without escaping through said openings. These o'ienings also serve as relief apertures whic water at that )oint in case the water in the sewer should ack up into the pipe or connection (l, owing to heavy rainfalls or other causes, thereby preventing overflowing of the water through a closet, cess pool or other receptacle connected with the sewer.

I claim as my invention 1. The combination of a lower pipe ad apted to be connected with a sewer, a gutter pipe, and a rotatable intermediate pipe telescopically connected with said pipes and vertical 7 movable on the lower pipe to a sufficient extent to disconnect its upper end from the gutter pipe, the intermediate pipe having a projection adapted to rest upon the lower pipe in the normal elevated position of the intermediate pipe, and the lower pipe havpermit the escape of the rid .d in

ing a longitudinal slot extending downward ipper edge and adapted to receive Jjection to permit the intermediate to e lowered on said slotted pipe. The combination of a lower pipe adaptto be connected with a sewer, a gutter a rotatable intermediate pipe teleiy connected with said pipes and ver- U novzible on the lower pipe to a su iiicient extent to disconnect its upper end from the gutter pipe, said lower pipe being proits upper edge with a locking notch 1 out of line with said notch with a longitudi .sl slot extending downward from said edge, and the intermediate pipe having a project-ion adapted to engage said locking notch to support and lock the intermediate pipe in its normal raised position and to enseid slot to permit the intermediate pipe to be lowered on said slotted pipe. I

The combination of a lower pipe adapted to be connected Wi li a sewer, a gutter pipe, a rotatable intermediate pipe teiescopically connected with said pipes and verti celly movable on the lower pipeto a Sufioient extent to disconnect its upper end from the gutter pipe, said intermediate pipe being provided near its upper end with an internei shoulder, below said shoulder with an enlargement having vent openings and below said enlargement with a projection, said lower pipe having?u longitiuilinal slot extending downward from its upper edge endedzipted to receive said projection, and a screen reinovnbly supported on said sliouli'ler.
